Noise May Raise Blood Pressure Risk

Airport noise could raise the risk for high blood pressure, a new study suggests. Greek researchers studied 420 people living near Athens International Airport, where an average of 600 airplanes take off and land every day. Maps made during construction of the airport divided the surrounding area by noise level: less than 50 decibels, 50 to 60 decibels (60 decibels is about the noise level of a room air-conditioner), and more than 60 decibels, so researchers could track noise exposure precisely. About two-thirds of the residents lived in the areas that regularly experienced noise at the 50- to 60-decibel level,…
